Title: Control of pulverizing mills
Inventor: TOOP GEORGE HERBERT
IPC: B02C25/00
Filed: 1950-09-01
Abstract: 682,478. Grinding and crushing mills. KENT, Ltd., G. Aug. 30, 1951 [Sept. 1, 1950], No. 21601/50. Class 59 A mill, particularly a ball mill or an edge-runner mill for pulverizing fuel, is controlled by measuring the rate of flow of the air which is passed through the charge in the mill to carry away pulverized material and also its pressure before and after the mill and, since the pressure differential, for a particular airflow, depends on the resistance afforded by the charge to the passage of air and, therefore, to the amount of the charge, these measurements can be used to vary automatically the rate of feed of material so as to maintain an optimum charge in the mill. Air is drawn or forced into the mill from hot and cold air inlets 7 and 8 and passes around the rotating pan 2 to carry the pulverized fuel through a centrifugal separator 9 to the exhauster fan 6. The air pressures at points 11 and 12 are applied to opposite faces of a diaphragm B and the pressure at 12 is also applied to one face of a diaphragm A to whose other face pressure from a pitot tube 10 is applied. The resultant forces on the diaphragms cause a beam C to adjust a pneumatic controller 13 and servo-motor 14 and the rheostat 15 so that a motor 5 driving a feeder 4 is appropriately controlled. The diaphragm deflections are constrained by a leaf spring D and the fulcrum of the beam is adjustable by a screw E. The pitot tube has its' bottom portion longitudinally cut away to give a shrouded opening facing downstream of the airflow.

Title: Improvements relating to mach-number meters
Inventor: DOVE FRANK
IPC: G01P5/175
Filed: 1956-07-12
Abstract: 796,910. Automatic speed-control systems. SPERRY GYROSCOPE CO., Ltd. July 12, 1958, No. 21631/56. Class 38 (4). [Also in Groups XXXVI and XXXVIII] A Mach number meter consists of apparatus which produces a signal the nature of which varies according to the Mach number of the aircraft, apparatus for producing a similar signal the quality of which varies in a similar manner to the above according to the setting of a pointer on a scale, and means for comparing these two signals. The difference between the signals may be used either to cause a servomotor to alter the setting of the pointer on the said scale until the scale reading coincides with the Mach number of the aircraft or to cause an alteration in the said Mach number of the aircraft until it coincides with the scale reading. A height unit 1 measures the static pressure and drives the variable contact 5 of potentiometer 3 by means of a servo mechanism 14 and an air-speed unit 2 measures the difference between dynamic and static pressure and uses the difference to drive variable contact 6 of the potentiometer 4 by means of servo 15. The resultant signal which is fed into resistor 9 is proportional to the difference between dynamic and static pressure divided by the static pressure. Similarly the signal which is fed into resistor 10 is a function of the position of the pointer 23. Resistances 7, 18 and 19 and their cross-tappings are so arranged that this latter function of position of the pointer is very similar to the function of the Mach number which yields the expression :- " difference between dynamic and static pressure divided by static pressure." Reference is made to modifications using inductive potential dividers, non-linear variation of the potential dividers 21, 22, and a non-linear scale at 8.

Title: Improvements in and relating to gas cushion vehicles
Inventor: SPILLMAN JOHN JAMES
IPC: B60V3/04
Filed: 1966-05-16
Abstract: 1,200,443. Railway systems: track propulsion. NATIONAL RESEARCH DEVELOPMENT CORP. 14 Aug., 1967 [16 May. 1966], No. 21695/66. Heading B7L. [Also in Division B8] A gas cushion vehicle 11, Figs. 1A and 1B, has on its underside a cushion chamber 13 provided with a plurality of vanes 14 and is supported above, guided and driven along a hollow track 18 by jets 15, of gas supplied from the track and passing through nozzles 16 in the upper surface 17 of the track, which jets engage the vanes 14. As shown in Fig. 2, the vanes 14 comprise fixed central vanes 19 and side vanes 21 forming nozzles 22. The invention is characterized in that the jets 15 impinge on the vanes 19 to give the vehicle a first component of motive thrust and exhaust through the nozzles 22 to give the vehicle a reaction second component of motive thrust, the gas supplied by the jets 15 in excess of that exhausted through the nozzles being effective to support the vehicle above the track and to co-operate with track guide walls 10 to laterally guide the vehicle. In the modified vehicle Fig. 3, the side vanes 21 comprise fixed portions 23 and adjustable tip portions 24, all of which may have settings 28, 26, or 27. The setting 28 of the tips 24 allows for rapid exhausting of the gas and thus to bring the vehicle into sliding braking contact with the surface 17. The setting 26 provides a reaction thrust assisting the thrust of the vanes 19. The setting 27 provides a reaction thrust in opposition to the thrust on the vanes 19 whereby the vehicle may be decelerated. Valve means may be providedfor each of the nozzles 16 whereby the latter, which are normally closed, are opened by gas pressure in turn as the vehicle moves along the track, after one nozzle at least has been mechanically operated. The invention is also applied to an endless conveyer belt as described with reference to Fig. 10 (not shown).

Title: Nuclear reactors
IPC: G21C17/108
Filed: 1973-05-07
Abstract: 1426267 Monitoring nuclear reactors SIEMENS AG 7 May 1973 [8 May 1972] 21734/73 Heading G6C In a system for monitoring a nuclear reactor (e.g. a PWR) a detector is mounted in the primary coolant circuit to monitor a reactor parameter and a displaceable probe can be introduced into the reactor by the actuation of control means responsive to the attainment of a preselected value of said parameter. As shown, detectors 5, 5<SP>1</SP> for measuring neutron flux are connected to a measuring device 7 whose output passes to an activating device 21 from which a signal is derived when the neutron flux measured attains a limit value. The pressure vessel 1 and core 2 are penetrated by tubes 10 which pass to measuring locations 11 at a station 14. Displaceable in the tubes 10 are probes 12 which may be balls, miniature ionization chambers, or helical spring elements. By appropriate actuation of valves 15, 16 the probes 12 are moved in the tubes 10 by pneumatic or hydraulic pressure. The valves 15, 16 are actuated by the signal from device 21 the signal being applied to the valve 16 via a delay element 25 so as to operate to return the probes 12 to the measuring positions 11 after a selected period of activation in the core 2. The in-core detectors may monitor other parameters, e.g. coolant pressure, and may monitor any parameter throughout the entire core or specific areas thereof. Probes 12 are associated with the outputs of the various detectors or detector groups so as to be displaceable independently for each different parameter or core area. Motor or magnetic drives can be used as alternatives to the pneumatic or hydraulic drives described. Where the signal from device 21 is maintained, to prevent repeated insertion of probes 12 into the core, latch means are provided. The control circuit of the system is described (Fig. 2, not shown).

Abstract: 671,754. Refuse vehicles; raising and tipping bins. DOORNE, H. J. VAN. Aug. 19, 1948. [Aug. 19, 1947] No. 21929/48. Class 78 (iv). A presser plate is oscillated about a horizontal shaft to compress refuse in a container on a vehicle and a holder for raising and tipping a dust bin is swung upwardly about the same shaft during upward movement of the plate so that the contents of the bin are discharged at the pressure side of the plate. As shown, a bin 25 is supported in a bin holder 24 hinged at 23 to a rocking member 21 which is free on a shaft 3. The shaft 3 is angularly oscillated by a lever 18, Fig. 1, formed with a slot 19 in which slides a member 20 secured to a chain 15 guided by arcuate guides 16, 17 and passing round sprockets 13, 14 the former of which is driven through gearing 12, 11, 9, 8 and a universal coupling 7 from a shaft 6 driven by the vehicle engine. A presser plate 4 carried with the shaft 3 engages, during its upward motion, the arms 21<SP>1</SP> by which the rocking member 21 is supported and raises the rocking member and the bin holder 24. During this motion a strut 27, Fig. 2, pivoted at 28 to the body of the vehicle and at 29 to an arm 26 on the hinge 23 carrying the bin holder tilts the latter so that the bin discharges through a hole in the rocking member 21 into a hopper 2 at the pressure side of the plate 4 which pushes the refuse into the main body of the vehicle on its return stroke. The lid 30 of the bin swings about its pivot 31 during tipping and hangs in the position shown at 30a in Fig. 2. The bin holder and bin are agitated in the discharging position by engagement of an arm 53 on the shaft 23 through a roller with the surface 51 of a bell crank 50 agitated by a rotating cam 48 : the strut 27 telescopes against a spring to permit this motion. Two lifting and tilting devices operable through independent clutches may be placed side-by-side at the rear of the vehicle. To prevent the lifting and tilting device being operated when no bin is on the bin holder 24, the arm 18 carries a cam which engages a member projecting through the wall 2a of the hopper 2 to cause it to push an intermediate member against a lever disengaging the clutch controlling the lifting and tilting device. When a bin is placed on the bin holder 24 a pin on the bin operates a linkage to remove the intermediate member so that the clutch is not disengaged.

Abstract: 1,037,275. Locking rotary elements. TELEMECANIQUE ELECTRIQUE. May 31, 1963 [Aug. 17, 1962], No. 21980/63. Heading F2E. [Also in Division H2] Interlocking mechanism for preventing simultaneous displacement of two displaceable elements, e.g. the moving contact-operating elements of a pair of electrical contactors C 1 , C 2 ,comprises a pair of rockable members L 1 ,L 2  each arranged to be rocked when an associated element is displaced, an arm provided on each member being arranged such that the two arms are offset from each other and crossed in the undisplaced condition of the elements, and projecting bosses 11 1 ,11 2 on these arms being so arranged that they do not normally interfere with each other when either of the elements is displaced without the other, but engage when any attempt is made to displace both elements simultaneously, or to displace one element after the other element has already been displaced. As shown, each rocking member consists of a shaft 8 which is journalled in a frame 7 supporting the pair of contactors C 1 ,C 2 and which carries the arm and also a pair of arms 9 which engage the lower ends of two contact-operating rods 5 of the associated contactor. The upper ends of rods 5 are connected by a resilient cruciform plate 4 to the contactor armature 3. The projecting bosses 11 1 ,11 2 have curved surfaces 14 1 ,15 1 ,14 2 ,15 2 respectively, the surfaces 14 1 ,152 being concentric with the axis of shaft 8 1 ,and the surfaces 14 2 ,15 1 ,being concentric with the axis of shaft 8 2 ,so that upon engagement of the bosses no camming action occurs which would cause a previously actuated contactor rod 5 to be returned to its unactuated position. A spring 12, tensioned between abutments 13 on the arms 10 1 ,10 2 ,maintains the rocker members in contact with the rods 5 and may also act as a common return spring for releasing the contactors.
